What is Quenching?

- Aug 28, 2017 -

Quenching is the rapid cooling of a material from an elevated temperature. It is generally intended to form martensite in steel. The minimum cooling rate to avoid the non-martensitic transformation of products is known as the critical cooling rate. Other common names and related subjects are: direct quenching, hot quenching, interrupted quenching, gas quenching, pressure quenching, selective quenching, spray quenching, and time quenching.
